DC is presently under an "epic" storm watch. So the local hordes are stripping the store shelves bare as I type this.
I believe 2 feet of snow is predicted for the Washington Area. A great opportunity to practice building a quinzhee and test your sleeping bag/bivi bag out perhaps.

Are there any hills nearby for a good toboggan run.
Give it a few weeks and the right conditions then even building an igloo might be a possibility depending of course if you get the right type of snow.
